## 2. Design Considerations
### 2.1 Common Design Pitfalls and Solutions
#### Pitfall 1: Improper Impedance Matching
Problem : Mismatched impedance leads to signal reflections and degraded performance
Solution :
- Use 50Ω transmission lines throughout the RF path
- Implement proper matching networks using simulation tools
- Include tuning pads for post-production optimization
#### Pitfall 2: Inadequate Grounding
Problem : Poor grounding causes unwanted oscillations and noise
Solution :
- Implement a solid ground plane directly beneath the component
- Use multiple vias for ground connections (minimum 4 vias per ground pad)
- Maintain continuous ground reference throughout the RF section
#### Pitfall 3: Thermal Management Issues
Problem : Overheating leads to performance degradation and reduced reliability
Solution :
- Include thermal vias under the component package
- Ensure adequate copper pour for heat spreading
- Consider forced air cooling for high-power applications
